HI all,I thought I had the security permissions and auto mount sorted. but maybe not!The Fstab content are below, but I have a drive that I want to leave open for the kids and another that only adults can get into. Unfortunately, whilst they do auto mount the permissions don't work, suggestions anyone?

This will limit access to the partition only to those members of the "adult" group. Each member will have the ability to add to and delete from the partition and all members will be able to write to each other's files. All new files by "adults" will save with group = adults and permissions of 664 which will enable all other member of the group to have write access to that file.

If that is not exactly what you had in mind or it goes too far in allowing access rights, you might want to look at this for other scenarios:HowTo: Multi User Shared Local Directory: viewtopic.php?f=42&t=69834

HI Altair,you do indeed have it right.I have 3 drives (2*NTFS and 1*ext4) which I want to sort out the permissions on. DataBackup (ext4)=adults only (Fstab line is "/dev/sda4 /media/DataBackup ext4 defaults,noatime 0 2")CMStore(NTFS)=adults only (Fstab line is "/dev/sdb1 /media/CMStore ntfs defaults,umask=002,uid=1000,gid=adults 0 0")DataNew(NTFS)=everyone full access, which works

Neither the DataBackup nor the CMStore prevent read access, although that does seem to be about it. I would prefer if they had no access at all, not that I don't trust them you understand

As far as the DataBackup partition the method I proposed in my previous post will do that. It will make it accessible only to the "adults". It will also make the contents of that partition writeable so that it will act like the CMStore partition.
